UNLOCKlNG-LEVER FOR CAR-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 491,388, dated February7, 1898.

Application filed July 8, 1892- Serial No. 489,410. (No model.)

as will enable others skilled in the art to which it appertains to makeand use the same.

My invention relates to an improvement in devices for use in connectionwith car couplore and more particularly to devices for un-' locking thecoupler,-the object of theinvention being to produce simple andefficient devices for manipulating the lock of a car coupler andmaintainiiiig said lock in an unlocked position at will.

With this object in view the invention cousistsin certain novel featuresof construction and combinations and arrangements of parts as hereinafterset forth and pointed out in the claims.

in the accompanying drawings: Figure 1 is a View in perspective showingmy improvements attached to the end sill of a car, showing" thepositions of the parts when the coupler lock isin its locked position.Fig. 2 is an end view showing the positions of the parts of myimprovement when the coupler lock is in its unlocked position. Fig. 3 isaview of a modification.

A represents the end sill of a car, to which a bracket B is secured andadapted to support one end of a revoluble bar O,-the other end of saidrevoluble bar being mounted in an elongated curved slot to in a bracketD, which latter is also secured to the end sillA. At the end of the rockbar 0 adjacent to the bracket 13 an arm E projects laterally therefromand is provided at its free end with a perforation b for the receptionof one end of a chain or cord 0, the other end of which is adapted to beattached to the lock of the coupler (not shown). Projecting from the endof the revoluble shaft 0 adjacent to the bracket D is an arm or lever E,said arm or lever E being bent to produce a short lever G, which, whenthe parts of the device are in position to maintain the lock of thecoupler raised or unlocked, will rest on a log or arm H projectinglaterally from the bracket 1).

Assuming the parts to be in the positions shown in Fig. 1 andthat it isdesired to raise the lock of the coupler and thus unlock the operationthe rock shaft or bar 0 will be forced backwardly through the curvedelongated slot 0; in the bracket (said rock bar or shaft 0 being mountedloosely in the bracket B, to permit-such movement), until said revolublebar passes the log or arm H on the bracket D. Then the parts are in thisposition, the end of the rock bar 0 will bear against the upper portionof the curved elongated slot, while the short lever will bear on the armor lug; H, thus preventing the rock bar from rotation and therebymaintaining the lock of the coupler raised or unlocked.

It is not necessary to force the rock bar O to the inner extremity ofthe curved elongated slot in the bracket D, in order to lock the partsin position, but said bar may be disposed just over the center of theslot and the short lever C made to bear on one edge of the lug or arm Has shown by dotted lines in Fig. 1.

From this construction and arrangement of parts it will be seen that thedevice may be set to hold the coupler lock in ail-unlocked position,regardless of the position in which the coupler may be placed in thecar.

The dotted lines in Fig. 1 indicate the positions in which the devicemay be disposed to maintain the coupler lock in an unlocked position.

The rock bar may, as shown in Fig. 3, be made fiat, as at f andaccomplish the same results.

The device is very simple in construction and effectual in theperformance of its functions.

Having fully described my invention what I claim as new and desire tosecure byLetters Patent is:

l. The combination with a pair of supporting brackets, of a rock barheld by said brackets, one of the brackets provided with an elongatedhorizontally disposed slot, a lug formed on said bracket below the slot,and an arm formed on the rock bar adjacent to the outer face of thebracket in position to rest directly upon the lug, substantially as setforth.

2. The combination with a pair of brackets, of a rock bar having twoarms thereon adjacent to the outer faces of the brackets whereby endwisemovement of the bar is prevented, one bracket provided with an elongatedhorizontally disposed slot and a lug on the outer face of said bracketadapted to form a stop for the adjacent arm of the rock bar,substantially as set forth.

3. The combination with a rock bar having an arm on its outer end, of apair of brackets for supporting this rock bar, one of said brack-
